What is the function of fly ash?
Fly ash is a kind of solid waste emitted by coal-fired power plants. In recent years, it has received widespread attention due to its environmental protection and resource utilization value. The following is a summary of hot topics and hot content about fly ash on the Internet in the past 10 days, and a detailed analysis of its functions.
1. Basic concepts of fly ash
Fly ash is the fine ash produced after coal combustion. Its main components are silica, alumina and iron oxide. According to the different combustion methods and collection methods, fly ash can be divided into two types: fly ash and bottom ash.
| Type | Features |
|---|---|
| fly ash | The particles are small and easy to collect, often used in building materials |
| bottom gray | Larger particles, usually used in road base materials |
2. Main functions of fly ash
Fly ash plays an important role in many fields, the following are its core applications:
| Application areas | Specific role |
|---|---|
| building materials | As an admixture for cement and concrete to improve strength and durability |
| Environmental protection project | Used for wastewater treatment, soil remediation, etc. |
| Agriculture | Improve soil structure and provide trace elements |
| Industry | Used to make ceramics, refractory materials, etc. |
